Title: Electromagnetic click wrenches
Inventor: PETER WILLIAM EVERITT
IPC: B25B23/144
Filed: 2019-08-15
Abstract: A click wrench comprising a shaft 6, a head 8 at the first end of the shaft and a handle 4 at the second end of the shaft. The wrench provides haptic feedback to an operator by permitting a small degree of relative movement between the handle and shaft when a predetermined torque value is reached. An electromagnet 12 and a pole piece locks the handle and the shaft against the relative movement until a trigger condition is satisfied. A method of providing haptic feedback to an operator of a click wrench involving selectively energising the electromagnet to lock the shaft to the handle opposing relative movement. If the torque is measured, then the trigger condition may be the predetermined torque value and the current supplied to the electromagnet may be limited to that required to resist the applied force at any given time. If the torque is not measured, then the current supplied to the electromagnet 12 may be set such that the force of the magnet will be overcome as soon as the predetermined torque value is reached.
